This aluminum AN hose clamp finisher sleeve is engineered for braided AN fuel, oil and coolant hoses, serving as both a securing component and decorative dress-up part for modified engine bays. Available in AN4, AN6, AN8, AN10 and AN12 sizes, it matches common braided fluid line specifications for automotive performance builds. Constructed from anodized aluminum with built-in stainless steel worm gear clamp, the sleeve delivers reliable clamping force while shielding the hose connection area. The adjustable screw structure allows convenient tightening after installation, creating a tidy, uniform appearance for exposed braided hose joints. The anodized surface offers solid resistance against corrosion under typical engine bay temperature and humidity conditions. Designed for fluid lines including fuel hoses, turbo oil supply lines and coolant pipes, this ferrule sleeve streamlines messy hose clamp layouts. It simplifies visual modification work for tuners, daily drivers and amateur racers. Users can select the corresponding size according to the outer diameter of their braided hose to achieve a snug fit. This aftermarket hose accessory is widely used for custom intake, cooling and fuel system builds. It combines practical clamping function with aesthetic upgrades, a cost-effective solution for enthusiasts looking to organize and beautify braided AN hose connections.
